The inner ring, roller complement and cage of a FAG NN3011-AS-M-SP double-row cylindrical roller bearing. Bore Diameter: 55 mm. Width: 26 mm. Number Of Rows: 2. Rolling Elements: Cylindrical Roller. Bore Type: straight cylindrical. Closure Type: Open. Cage Material: Brass, machined. Precision: SP, ISO class 5 (P5, ABEC 5). Unit Quantity: 1 Pc. Inner ring with roller and cage assembly only. No outer ring.
NN — double-row cylindrical roller design with the three guide ribs on the inner ring and a plain separable outer ring. The reverse arrangement, ribs on the outer ring, is NNU.
30 — dimension series.
11 — bore code, 55 mm at five millimetres per unit. A complete NN3011 measures 55 x 90 x 26 mm.
AS — FAG lubrication groove with radial feed holes, machined into the outer ring.
M — machined brass cage.
SP — FAG special precision: dimensional tolerance to ISO class 5, equivalent to P5 and ABEC 5, with running accuracy held tighter than class 5.
No K suffix — straight cylindrical bore.
Bore Diameter: 55 mm. Width: 26 mm. Series: NN3000. Number Of Rows: 2. Rolling Elements: Cylindrical Roller. Cage Material: Brass. Cage Type: Machined. Precision Rating: ABEC 5 / P5. Material: Chrome Steel. Harmonization Code: 8482.50.00.00.
Two rows of cylindrical rollers in a narrow section give very high radial rating and radial stiffness for the width. The bearing locates the shaft radially; axial location comes from a separate thrust or angular contact bearing. The machined brass cage suits the speed, temperature and lubricant drag of a precision spindle. The roller set travels with the inner ring and enters a plain outer ring axially.
ISO base number NN3011. Cross-references: SKF NN 3011 TN/SP and NSK NN3011MB, inner ring and roller assemblies at class 5 precision with a machined brass cage. Matching part: the plain outer ring of an NN3011, 90 mm outside diameter, with the AS lubrication groove and feed holes. NNU4911 is a related size with ribs on the outer ring. NN3011K is the 1:12 tapered-bore form.
The inner ring with its two roller rows and machined brass cage. No outer ring.
55 mm bore and 26 mm width; a complete NN3011 is 55 x 90 x 26 mm.
SP, ISO class 5, equivalent to P5 and ABEC 5.
